4.1 Remote Monitoring, Autochangeover and Leak Detection EquipmentThe Liebert RCM4 is a four-point, normally open, dry contact monitoring panel. One Form-C, dry contact common alarm relay output (rated at 24 VAC, 3 Amp) is provided. Four red LEDs illuminate on the respective alarm and the alarm buzzer is silenced by a front panel switch. The RCM4 requires a 24VAC or 24VDC power source. Power supply is not included.

The Liebert AC4 Autochangeover Controller provides autochangeover and autosequence control for up to four Liebert DataMate units within a room. The Liebert AC4 will enable redundant units in an alarm condition, balance usage and test standby units at programmed intervals. Two common alarm relay outputs are available. A built-in LCD and RS-232 port for direct PC/terminal connection provides two options for configuration and monitoring of the product. The Liebert AC4 requires 24VAC input power.

The Liebert AC8 is ideal for coordinated control of systems with redundant units. The Liebert AC8 enables redundant devices during an alarm condition, balances usage of devices and tests standby devices at programmable intervals. Supports four zones and can use the 4-20mA temperature sensor (TW420) for temperature staging in each zone. Two programmable output control relays are available for auxiliary control such as humidity lockout. Emergency power operation input provided for device control during an emergency. Two common alarm relay outputs are available. A built-in LCD and RS-232 port for direct PC/terminal connection provides two options for configuration and monitoring of the product.

NOTEWhen installing remote condensing units below the evaporator, the suction gas line should be trapped with an inverted trap to the height of the evaporator . This prevents refrigerant migration to the compressors during off cycles . Maximum recommended vertical level drop to condensing unit is 15 ft. (4.6m) .
